Add options argument to register functions to pass to pirates

[gordonmleigh]

Further to #571, this PR exposes the new addHook options argument to the register* functions too.

Would you consider making the register functions available via the index, so they can be imported without a deep package reference (currently 'sucrase/dist/register')? I can add to this PR or another. If we do this I'll also update the readme to document these functions.

Thanks for the quick merge on the other PR!

Unfortunately I think this would break Sucrase in the browser since it would mean a regular Sucrase import would pull in pirates, which seems to have a hard dependency on a node environment. I tested it with these steps and saw a webpack failure:

yarn build
yarn link
cd website
yarn link sucrase
yarn start
...
Module not found: Error: Can't resolve 'module' in '/Users/alanpierce/code/sucrase/node_modules/pirates/lib'

(The package named "module" is built into node, and pirates expects it to exist.)

I might be missing an alternate approach, though; happy to hear suggestions. Another high-level option would be to refactor out @sucrase/register and @sucrase/cli packages, though IMO it's nice for the basic things to be "batteries included".

Thanks! As I mentioned, I'm unsure about the best way to export these functions in a cleaner way, so I'll merge this step and happy to discuss the other stuff separately.
